complishing the desired result. As shown, the atomizing device consists of upper and lower metal plates or disks A and A? having therebetween asheet of asbestos or similar material B and having spacedopenings C therethrough, preferably arranged in circular series or rows between the center and circumference of the disk. Said openings are formed by slitting the metal plates at intervals and pressing the metal upwardly on one side of the slit and downwardly on the other side thereof, so as to form or provide oblong or oval-shaped open- 1 oo vrrosrrrifsrnnY-rnn'rn.

riphe'ry of 5 the, platei showma V A spray plate of thei-rdescribedw eonstru tion, havinga layer of asbestos or other heat-resisting material between .two metallic plates, possesses better heat-resisting qualities than a single plate, is stronger, and is less liable to be warped whensubjected to intense heat, and the life of the plate is much longer than that of a sin le'plate, which easily warps and is not well adapted to withstand the intense heat to which such devices are subjected in oil burners of the class with which signed to be used.

In operation, as

such spray plates are dethe spray plate rapidly rotatedin the direction of the arrows in Fig. 1, the oil is thrown outwardly by the combined action of the centrally disposed blades and the raised portions ofthe spray plate,

together with commingled air onto the inclined peripheral blades and is further broken up and atomized by the action of the last mentioned series of blades, and'by reason of the peculiar form of the openings through thespray plate andthe combined action of the inclined blades, a Whirlwind effect is produced, and a thorough atomization of the oil and commingling of the vapor with air is effected, for feeding the burner. and maintaining a heating blazev thus producing more perfect combustion with less. waste of fuel than is usual in the operation of rotary oil burners.

WVhile the spray plates are preferably formed or provided with the inclinedblades. at the circumference thereof, and also near the center, or on opposite sides of the circular series of openings, one or both sets of blades may be omitted, and a greater or less number of rows of openingsmay be formed in the spray plate and various 'changes may be made in the details and arrangement of parts without departing from the spirita'nd scope of myinvention, and I therefore do not desire to be limited to the specific construc tion'shown and described.

Having thus described my invention, what I claimas new anddesireto secure by Letters Patent is:

1. A composite spray plate for :rotary oil burners'comprisingia' plurality of disks having circular seriesof openings therethrough. of ovalshaped form arranged .to effect the passage offiuid therethrough substantially I .lIl the plane'of' the disk, and a sheet of as- 2. A composite spray plate for rotary oil burners comprising a plurality of disks and bestos or similar reinforcing and heat-resist ing material between s'aiddisks having oblongopeningsft'herein which register with the openings through the disks.

an interposed sheet of asbestos or similar reinforcing and heat-resisting material having registering openlngs therethrough which are oblonginv form andhave their axes ex- 7 tending 5 O on horizontal lines substantially in the plane of the plate.

substantially in the plane of the plate; said raised and depressed portions 'gbeing substantially concavo-convex and having their concave surfaces facing at theentrance to said openings and tapering as they recede therefrom and merging in the surface of the plate said plates having a sheet of asbestos or similar reinforcing and heat-resisting mate rial placed therebetween and said sheet having openings therethrough which register with the openings inthe plates. Y

4:; A composite spray plate for rotary oil burners comprising'a plurality of disks hav-' ing asheet of asbestos or similar reinforcing and heat-resisting material therebetween',

said disks and sheet having registering openings therein whose axes extend substantially in the plane of the plate; the upper plate having, thereon vertically disposed blades arranged at an angle to and encircling its. axis, and the composite plate having a series of blades arranged at an around its periphery. y 1

5. An atomizing device for rotary'i oil burners consisting of a plurality of metal plates each slitted at intervals around its axis and having the metal upraised. on one side of'the slit and depressed on the other side thereof so as'to form openings having their axes extending substantially in the plane of the plate; said raised and depressed portions having i concave surfaces facing at the mouth of said openings, and a sheet of asangl'e theretobestos or other reinforcing and heat-resisting material between'saidfplates having openings therein coincident with the openings in said plates.
